You may need a new license file. When changing hardware on a machine the MAC Address also changes. Compare the MAC Address within the license file to your NIC card information. To get the NIC info, go to Start and type “cmd” in the search box. When the command prompt is displayed, type “ipconfig /all”
If the MAC Addresses are different, request a new license file by logging into registeronce.autodesk.com
Hope that helps.
We didn´t change the hardware in the machine. What we got is a new router from our internet provider because the one we had stopped working. It is very strange that it worked the other day and now its back to having the same error. We need help!
Check to see if your firewall is enabled. If so, disable it and try running the application again.
